Wifi连接+列表展示+防苹果弹窗输入密码连接

本人在这个项目中用到wifi扫描+连接，本想着偷懒省事去网上找，始终没有找到合适的就自己写了一篇，有不足请大神指出！

话不多说，上代码！

MainActivity主页面：

非常实用的WiFi工具类：

public class WifiAdmin {
    // 定义WifiManager对象
    private WifiManager mWifiManager;
    // 定义WifiInfo对象
    private WifiInfo mWifiInfo;
    // 扫描出的网络连接列表
    private List<ScanResult> mWifiList;
    // 网络连接列表
    private List<WifiConfiguration> mWifiConfiguration;
    // 定义一个WifiLock
    WifiManager.WifiLock mWifiLock;


    // 构造器
    public WifiAdmin(Context context) {
        // 取得WifiManager对象
        mWifiManager = (WifiManager) context
                .getSystemService(Context.WIFI_SERVICE);
        // 取得WifiInfo对象
        mWifiInfo = mWifiManager.getConnectionInfo();
    }

    // 打开WIFI
    public void openWifi() {
        if (!mWifiManager.isWifiEnabled()) {
            mWifiManager.setWifiEnabled(true);
        }
    }

    // 关闭WIFI
    public void closeWifi() {
        if (mWifiManager.isWifiEnabled()) {
            mWifiManager.setWifiEnabled(false);
        }
    }

    // 检查当前WIFI状态
    public int checkState() {
        return mWifiManager.getWifiState();
    }

    // 锁定WifiLock
    public void acquireWifiLock() {
        mWifiLock.acquire();
    }

    // 解锁WifiLock
    public void releaseWifiLock() {
        // 判断时候锁定
        if (mWifiLock.isHeld()) {
            mWifiLock.acquire();
        }
    }

    // 创建一个WifiLock
    public void creatWifiLock() {
        mWifiLock = mWifiManager.createWifiLock("Test");
    }

    // 得到配置好的网络
    public List<WifiConfiguration> getConfiguration() {
        return mWifiConfiguration;
    }

    // 指定配置好的网络进行连接
    public void connectConfiguration(int index) {
        // 索引大于配置好的网络索引返回
        if (index > mWifiConfiguration.size()) {
            return;
        }
        // 连接配置好的指定ID的网络
        mWifiManager.enableNetwork(mWifiConfiguration.get(index).networkId,
                true);
    }

    public void startScan() {
        mWifiManager.startScan();
        // 得到扫描结果
        mWifiList = mWifiManager.getScanResults();
        // 得到配置好的网络连接
        mWifiConfiguration = mWifiManager.getConfiguredNetworks();
    }

    // 得到网络列表
    public List<ScanResult> getWifiList() {
        return mWifiList;
    }

    // 查看扫描结果
    public StringBuilder lookUpScan() {
        StringBuilder stringBuilder = new StringBuilder();
        for (int i = 0; i < mWifiList.size(); i++) {
            stringBuilder
                    .append("Index_" + new Integer(i + 1).toString() + ":");
            // 将ScanResult信息转换成一个字符串包
            // 其中把包括：BSSID、SSID、capabilities、frequency、level
            stringBuilder.append((mWifiList.get(i)).toString());
            stringBuilder.append("/n");
        }
        return stringBuilder;
    }

    // 得到MAC地址
    public String getMacAddress() {
        return (mWifiInfo == null) ? "NULL" : mWifiInfo.getMacAddress();
    }

    // 得到接入点的BSSID
    public String getBSSID() {
        return (mWifiInfo == null) ? "NULL" : mWifiInfo.getBSSID();
    }

    // 得到IP地址
    public int getIPAddress() {
        return (mWifiInfo == null) ? 0 : mWifiInfo.getIpAddress();
    }

    // 得到连接的ID
    public int getNetworkId() {
        return (mWifiInfo == null) ? 0 : mWifiInfo.getNetworkId();
    }

    // 得到WifiInfo的所有信息包
    public String getWifiInfo() {
        return (mWifiInfo == null) ? "NULL" : mWifiInfo.toString();
    }

    // 添加一个网络并连接
    public boolean addNetwork(WifiConfiguration wcg) {
        mWifiManager.disconnect();
        int wcgID = mWifiManager.addNetwork(wcg);
        boolean b =  mWifiManager.enableNetwork(wcgID, true);

        System.out.println("a--" + wcgID);
        System.out.println("b--" + b);

        return b;
    }

    // 断开指定ID的网络
    public void disconnectWifi(int netId) {
        mWifiManager.disableNetwork(netId);
        mWifiManager.disconnect();
    }

主MainActivity布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                tools:context=".MainActivity" >

    <ListView

        android:id="@+id/listView"

        android:layout_width="match_parent"

        android:layout_height="wrap_content" >

    </ListView>



</RelativeLayout>

列表item布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <TextView
        android:layout_centerInParent="true"
